I'll bet you are chunking out a lot of files.  If so, then
you are probably I/O bound.  I get similar results on
Windows XP when chunking a big book, but xsltproc is about
2.5 times faster when I use the non-chunking stylesheet on
the same book.  That suggests it is the opening, writing,
and closing of files that is equalizing the two.

On my Linux box with a slower CPU speed, the speed ratio is
about 5 times, whether I'm chunking or not.  I think in
that case the filesystem is staying sufficiently ahead of
the processor to show the diffence between the
two processing engines.
